c) x^4+x^3+9x+3

d) -x^4+x^3-9x+3

2) what is the degree of the polynomial
3pq^4-2p^2q+q^3?

a) 1

b) 2

c) 4

d) 5

3) which expression is not a polynomial?

a) z+1

b) 2x^4-y

c) 6+w

d) y^2-^3√y+4

See below.

Step-by-step explanation:

1).  Standard form is where the exponents are arranged in descending order.

It's D.   -x^4+x^3-9x+3.

2)

D.  Degree 5 because the term with the highest degrees is 3pq^4.

3)

Its D,  because of the radical √y.

c

step-by-step explanation:

it isn't d, because the interquartile range is from 27-57. and the interquartile range is basically half the data, it's pretty obvious.

it isn't b, because like i said earlier, the interquartile range is from 27-57. 57-27 is 30. the real range has to be longer

not a either. although it looks like it, 3/4 of the data is not greater than 27. but if c is wrong than this should be correct

the correct answer is c, because 13 is the point in which the plot starts
